The American actress plays a Yorkshire girl Emma in her new movie 'One Day' but the 28-year-old star insists she was more comfortable stripping off for a skinny dipping scene with her co-star Jim Sturgess than speaking in her character's regional dialect.

Anne – who has taken off her clothes for parts in 'Havoc', 'Brokeback Mountain' and 'Love And Other Drugs' - said: "I was more nervous about the accent than nudity.

"I mean, you can do sit-ups as prep for the nudity. But there aren't a lot of vocal sit-ups that you can do. Maybe it's because I have more experience in my life being naked than pretending to be British._______________________Read more:

"So I got more comfortable quickly with the nudity than I did with the accent."

Despite her difficulties, the actress – who was born in New York and raised for most of her childhood in New Jersey - worked hard at mastering the accent, but was disappointed that she never dreamt in her British voice.

Anne – who read the book 'Watching the English: the Hidden Rules of English Behaviour' to held her with her accent – told The Sun newspaper: "I stayed in the accent and used British-isms. I was a little disappointed because I hoped I would start dreaming in the accent.

"That one morning I would just wake up and be in the accent. But that never happened. But once I was in it, the American accent became the 'other'. It was hard to mix the two so I just wound up staying in it all the time. At the wrap party it freaked people out when I started talking like me."
